Symfony Dotenv parses .env files to make environment variables stored in them accessible via $_SERVER or $_ENV.
composer require symfony/dotenvuse Symfony\Component\Dotenv\Dotenv; $dotenv = new Dotenv(); $dotenv->load(__DIR__.'/.env'); // you can also load several files $dotenv->load(__DIR__.'/.env', __DIR__.'/.env.dev'); // overwrites existing env variables $dotenv->overload(__DIR__.'/.env'); // loads .env, .env.local, and .env.$APP_ENV.local or .env.$APP_ENV $dotenv->loadEnv(__DIR__.'/.env');
